FIELD: physics, optics.
SUBSTANCE: invention relates to a method for holographic rendering of high-speed processes - two-phase "solid particle - gas" streams. When carrying out the method using optical elements, two object and two reference beams are formed. The first object beam passes through the stream and the second is diffusely reflected, for example, from the surface of a body moving in the stream. A first hologram obtained using the first object beam enables to study the structure of the two-phase stream. A second hologram obtained using the second object beam enables to evaluate the state of the surface of the object. The two holograms are recorded simultaneously.
EFFECT: recording two holograms in one exposure, one of the holograms corresponding illumination of the analysed object and the second corresponding to diffuse reflection therefrom.
